THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT
NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT
ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR
THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION
PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO
LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television
reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in
part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class
A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct
any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco
equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by
using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television
or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Product Overview
Switch Description
The Catalyst 2948G switch has 48 autosensing and autoconfiguring
10/100BASE-T Fast Ethernet fixed ports. The Catalyst 2948G-GE-TX switch has
48 autosensing and autoconfiguring 10/100/1000BASE-T ports. The
Catalyst 2980G switch has 80 autosensing and autoconfiguring 10/100BASE-T
Fast Ethernet fixed ports.
GBIC Module Support
The Catalyst 2948G and 2980G switches each have two Gigabit Ethernet uplink
ports with modular Gigabit Interface Converters (GBICs).
A GBIC is a hot-swappable input/output device that plugs into a Gigabit Ethernet
port module and links the port module with a fiber-optic network. For a detailed
description of Gigabit Ethernet ports, see the “GBIC Features” section on
page 4-2.
For a complete list of supported GBIC modules, see Table 4-1 on page 4-3.
Note
The Catalyst 2948G-GE-TX switch does not support GBIC modules.
The Gigabit Ethernet ports can be configured with any combination of GBIC
types.
The Gigabit Ethernet ports on these modules are used primarily for backbone
interconnection of other high-performance switches and routers.
SFP Module Support
The Catalyst 2948G-GE-TX switch has four small form-factor pluggable (SFP)
module slots. The switch uses SFP modules to establish Gigabit connections. The
SFP module slots are located on the front of the switch.
An SFP module is a hot-swappable input/output device that plugs into an SFP
module slot, linking the port module with a fiber-optic network.
For a list of SFP modules supported by the Catalyst 2948G-GE-TX switch, see
Table 4-4 on page 4-12.

Product Overview
Switch Description
Note
Catalyst 2948G-GE-TX switch only supports 1000 Mbps and full-duplex modes
on SFP modules.
Except for the 1000BASE-T SFP module, all of the SFP modules are used to
establish fiber-optic connections. You use fiber-optic cables with Lucent (LC)
connectors to connect to an SFP module. The SFP modules support 850 to 1550
nanometer nominal wave lengths. These field-replaceable modules provide the
uplink optical interfaces, laser send (TX) and laser receive (RX). For a detailed
description of Gigabit Ethernet ports see the “Connecting To an SFP Module”
section on page 4-12.

Power Supplies
There is no power switch on the switches. AC power is present in the power
supply when the power cord is plugged in.
The environmental monitoring and reporting functions allow you to maintain
normal system operation by correcting adverse environmental conditions before
loss of operation.
Each power supply monitors its own temperature and output voltages. If the power
supply becomes excessively hot, it shuts down to prevent damage. The switches
monitor the operating condition of the power supply and report the status using
switch software.
The switches have the following power supplies:
Note
•
120 W AC internal power supply—Catalyst 2948G switch
•
156 W AC internal power supply—Catalyst 2948G-GE-TX switch
•
175 W AC internal power supply—Catalyst 2980G switch
•
156 W AC internal power supply—Catalyst 2980G-A switch
For complete power specifications for the Catalyst 2948G, 2948G-GE-TX,
and 2980G switches, see Appendix A, “Specifications.”
These switches also be used with an optional Cisco Redundant Power System
(RPS).

Chapter 1
Product Overview
Switch Components
•
The Catalyst 2948G switch uses the Cisco RPS 600 AC power supply
(PWR600-AC-RPS-CAB).
The Cisco RPS 600 supports four external devices that use up to 150 W DC
each. Use a one-to-one cable (one connector at each cable end) to connect
four external devices to the four DC output power modules.
The power source is partially redundant. There are two AC input power
modules for the Cisco RPS and one DC output power module for each
external device. The AC input to the Cisco RPS is fully redundant, but the DC
output to the external devices is not.
Warning
Attach only the Cisco RPS (model PWR600-AC-RPS) to the RPS receptacle.
Statement 112
•
The Catalyst 2948G-GE-TX switch uses the Cisco RPS 675 (model
PWR675-AC-RPS-N1).
The RPS 675 supports six external network devices and provides DC power
to one failed device at a time. It automatically senses when the internal power
supply of a connected device fails and provides power to that device, which
prevents loss of network traffic.
Warning
Attach only the Cisco RPS (model PWR675-AC-RPS-N1=) to the RPS receptacle.
Statement 100C
•
The Catalyst 2980G-A switch uses the Cisco RPS 300
(PWR300-AC-RPS-N1).
The RPS 300 supports six external network devices and provides power to
one failed device at a time. It automatically senses when the power supply of
a connected device fails and provides the necessary power to the failed device
to prevent loss of network traffic. When the internal power supply of the
device has been brought up or replaced, the RPS automatically stops
powering the device.
Warning
Attach only the Cisco RPS (model PWR300-AC-RPS-N1) to the RPS receptacle.

Chapter 1
Product Overview
Switch Components
A Cisco RPS can only power one switch at a time. If more than one switch fails
at the same time, any subsequent switch is not supported by the RPS until the first
switch failure is resolved. For more information, refer to the documentation that
was included with your RPS.
On the Catalyst 2948G switch, you must use a Y cable to connect the switch to
two RPS 600 power supplies. Each RPS 600 has status LEDs (PSI and RPS).
On the Catalyst 2980G-A switch, each RPS 300 power supply has an individual
power cord and has status LEDs (PSI, PWR, and RPS).
The RPS uses redundant power supplies. If one of the power supplies in the RPS
fails, the RPS will automatically switch over to the other power supply without
forcing the switch to reboot.
Note
On the Catalyst 2948G-GE-TX and 2948G switches, only one power source can
supply power to the switch at any one time. When you are using an RPS, unplug
the local power cord for the switch. If you are using the local power supply, the
RPS can be connected but must not be powered on. The switches can be powered
by both the internal power supply and the RPS at the same time.

Before you connect the power supply to a power source, ensure that all site power
and grounding requirements described in “Site Planning” section on page 2-1
have been met.
Step 2
Plug the power cord into the chassis.
Step 3
Connect the other end of the power cord to an AC-power input source.
Step 4
Verify power supply operation by checking the front panel power supply LEDs:
•
When the power supply is operational, the LED is green.
•
When the power supply has failed, the LED is amber.
From the system console, enter the show system command to display the power
supply and system status. For more information on commands, refer to the
command reference for your switch.

If the LEDs or the show system command indicate a power problem or other
system problem, see Appendix D, “Translated Safety Warnings” for more
information.
Connecting to 10/100 and 10/100/1000 Ports
The 10/100 ports on the Catalyst 2948G and 2980G switches configure
themselves to operate at the speed and duplex settings of attached devices. They
operate at 10 or 100 Mbps in half- or full-duplex mode. If the attached devices do
not support autonegotiation, the speed should resolve correctly. You can also
explicitly set the speed and duplex parameters.
The 10/100/1000 ports on the Catalyst 2948G-GE-TX switches configure
themselves to operate at the speed setting of attached devices. These ports operate
at 10, 100, or 1000 Mbps in full-duplex mode. If the attached devices do not
support autonegotiation, you can set the speed.
Connecting devices that do not autonegotiate or devices with manually set speed
and duplex parameters can reduce performance or result in link failures between
the devices. To maximize performance, choose one of these methods for
configuring the ports:
•
Allow the ports to autonegotiate both speed and duplex for 10/100 ports and
only speed for 10/100/1000 ports.
•
Set the speed and duplex parameters on both ends of the connection.
Caution
To comply with the intrabuilding lightning surge requirements, intrabuilding
wiring must be shielded, and the shield for the wiring must be grounded at both
ends.
Caution
To prevent electrostatic-discharge (ESD) damage, follow your normal board and
component handling procedures.

Connecting a Terminal to the Console Serial and Ethernet Management Ports
Step 3
Observe the port STATUS LED:
•
The LED turns amber while Spanning Tree Protocol (STP) discovers the
network topology and searches for loops. This process takes about 30
seconds.
•
The LED turns green when the switch and the target device have an
established link.
The LED does not light when the target device is not turned on, a cable problem
exists, or a problem exists with the adapter installed in the target device.
If the STATUS LED does not turn green or does not light at all, see
“Troubleshooting the Installation” section on page 5-1 for solutions to cabling
problems.
Step 4
Reconfigure and restart the target device if necessary.
Step 5
Repeat Steps 1 through 4 to connect each port.
Connecting a Terminal to the Console Serial and
Ethernet Management Ports
The console serial and Ethernet management ports are located on the front panel
of the Catalyst 2948G, 2948G-GE-TX, and 2980G switches. These ports use an
RJ-45 media-dependent interface crossed-over (MDIX) connector, as shown in
Figure 3-16. For information about port pinouts, see Appendix A,
“Specifications.”
The Catalyst 2948G switches have a 10BASE-T management port. The
Catalyst 2948G-GE-TX and 2980G-A switches have a 10/100BASE-T
management port.
Note
The MDIX Ethernet ports are crossed over internally. For an MDI-to-MDI or
MDIX-to-MDIX connection, use a crossover cable. For an MDI-to-MDIX
connection, use a straight-through cable, which allows the Tx pins to connect with
the Rx pins.

Verifying Switch Operation
After you have connected all the interfaces, check all connections, and then
perform the following steps to power on the system to verify that it is operational:
Step 1
Before powering on the system, make sure the connector is installed securely in a
grounded outlet at the power-source end of the power cord and that the source
power is within the range labeled on the back of the switch. When two power
supplies are present, make sure that the second cord is connected to a separate line
from the first, if possible.
Step 2
Check the console terminal and make sure it is powered on.
Step 3
Connect the power cords to the switch.
Step 4
Verify that the PSI or PWR LEDs on the power supply front panel is green.
Step 5
Listen for the system fans to ensure that they are operational.
Step 6
While the system initializes, check that the STATUS LED on the supervisor
engine is amber until the boot is complete.
Note
Many of the interface LEDs do not illuminate until you configure the
interfaces.
When the system boot is complete (it takes a few seconds), the supervisor engine
begins to initialize the interfaces. During this initialization, the interface LEDs
flash on and off. When initialization is complete, the console screen displays a
script and system banner.

Chapter 4
Configuring the Gigabit Ethernet Ports
Installing, Removing, and Maintaining GBICs
•
When using the 1000BASE-LX/LH GBIC with 62.5-micron diameter MMF,
you must install a mode-conditioning patch cord between the MMF
fiber-optic network and the GBIC. The mode-conditioning patch cord
(CAB-GELX-625 or equivalent) is required to comply with IEEE standards.
See the “Patch Cord” section on page 4-10 for more information.
•
You must insert a 10-dB inline optical attenuator between the single-mode
fiber-optic network and the receiving port on the 1000BASE-ZX GBIC at
each end of the link if the link length is less than 15.5 miles (25 km).
•
You must insert a 5-dB inline optical attenuator between the single-mode
fiber-optic network and the receiving port on the 1000BASE-ZX GBIC at
each end of the link if the link is greater than 15.5 miles (25 km), but less than
31 miles (50 km).
Installing GBICs
This section describes how to install GBICs.
Caution
Unnecessary removal and insertion of a GBIC could lead to premature failure of
the GBIC. A GBIC has a lifetime of 100 to 500 removals and insertions.
A switch can be shipped with or without GBICs installed.
Caution
Note
When removing or inserting a GBIC, always wear an ESD wrist strap connected
to the ESD wrist strap connector. For more information about ESD, refer to the

GBIC Maintenance Guidelines
Follow these GBIC maintenance guidelines:
•
GBICs are static sensitive. To prevent ESD damage, follow your normal
board and component handling procedures.
•
GBICs are dust sensitive. When the GBIC is stored or when a fiber-optic
cable is not plugged in, always keep plugs in the GBIC optical bores.
•
The most common source of contaminants in the optical bores is debris
picked up on the ferrules of the optical connectors. Use an alcohol swab or
Kim-Wipe to clean the ferrules of the optical connector.
Patch Cord
When using the LX/LH GBIC with a 62.5-micron diameter core size MMF, you
must install a mode-conditioning patch cord (Cisco product number
CAB-GELX-625 or equivalent) between the GBIC and the MMF cable on both
the transmit and receive ends of the link. The patch cord is required for link
distances greater than 984 feet (300 meters).
Note
We do not recommend using the LX/LH GBIC with MMF without a patch cord
for very short link distances (tens of meters). The result could be an elevated bit
error rate (BER).
Note
The patch cord is required to comply with IEEE standards. The IEEE found that
link distances could not be achieved with certain types of fiber-optic cable due to
a problem in the center of some fiber-optic cable cores. The solution is to launch
light from the laser at a precise offset from the center by using the patch cord. At

a short link distance can cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH
SFP module with 62.5-micron diameter MMF, you must also install a mode-conditioning patch cord between the SFP module
and the MMF cable on both the sending and receiving ends of the link. The mode-conditioning patch cord is required for link
distances greater than 984 feet (300 m).
2. 1000BASE-ZX SFP modules can reach up to 100 km by using dispersion-shifted SMF or low-attenuation SMF; the distance
depends on the fiber quality, the number of splices, and the connectors.
Note
For information about the Coarse Wave Division Multiplexing (CWDM), refer to
the Cisco CWDM GBIC and CWDM SFP Installation Note.
The 1000BASE-T (copper) SFP module is used to establish a Gigabit Ethernet
connection through a Category 5 Category 5 cable.
Use only Cisco SFP modules on the Catalyst 2948G-GE-TX switch. Each SFP
module has an internal serial EEPROM that is encoded with security information.
This encoding provides a way for Cisco to identify and validate that the SFP
module meets the requirements for the switch.

Caution
Do not remove the rubber plugs from the ports on fiber-optic SFP modules or the
rubber caps from the the fiber-optic cable until you are ready to connect the cable.
The plugs and caps protect the SFP module ports and cables from contamination
and ambient light.
Before connecting to an SFP module, be sure that you understand the port and
cabling stipulations in Table 4-5. See Appendix A, “Specifications,” for
information about the LC on the SFP modules for fiber-optic connections.
Follow these steps to connect a fiber-optic cable to an SFP module:
Warning
Invisible laser radiation may be emitted from disconnected fibers or
connectors. Do not stare into beams or view directly with optical instruments.

Troubleshooting the Installation
This chapter describes how to troubleshoot the Catalyst 2948G, 2948G-GE-TX,
and 2980G switch installations. It contains these sections:

Getting Started, page 5-2
•
Problem Solving to the System Component Level, page 5-2
•

If you have problems starting up your system, use the information in this chapter
to help isolate the cause. Problems with the initial startup are often caused by poor
or improper connections. Temperature conditions above the maximum acceptable
level are rarely the source of problems at startup; however, environmental
monitoring functions are included in the following sections because they also
monitor DC-line voltages.
For configuration questions or problems, refer to the software configuration guide
or the command reference for your switch.

Chapter 5
Troubleshooting the Installation
Getting Started
Getting Started
When the initial system boot is complete, verify the following:
•
Power supplies are supplying power to the system.
•
On Catalyst 2948G and 2980G switches, the system fan assembly is
operating.
•
On Catalyst 2948G-GE-TX switches, the blower is operating.
If all of these conditions are met and the hardware installation is complete, refer
to the software configuration guide and the command reference for your switch to
troubleshoot the software. However, if any of these conditions is not met, use the
procedures in this chapter to isolate and, if possible, resolve the problem.
Problem Solving to the System Component Level
The key to success when troubleshooting the system is to isolate the problem to a
specific system component. The first step is to compare what the system is doing
to what it should be doing. Because a startup problem can usually be attributed to
a single component, it is more efficient to isolate the problem to a subsystem
rather than troubleshoot each component in the system separately.
The switch consists of the following subsystems:
•
Power supply—Includes the power supplies and power supply fans (see
“Troubleshooting the Power Supply” section on page 5-4)
•
Fans—The fan assembly should operate whenever system power is on. The
fan assembly continues to operate even when the environmental monitor
shuts the system down because of an overtemperature or overvoltage
condition (although it will shut down in the event of a power supply
shutdown).
The following are simple checks you can make to determine if there is a fan
problem:
•
Determine if the software is reporting a temperature problem.
•
Listen to the fan assembly to determine if it is operating.
•
Check for any obstructions that might be restricting the airflow through the
switch.

Troubleshooting the Installation
Identifying Startup Problems
If you encounter a problem in performing any of the above checks, you should
contact a customer service representative.
Identifying Startup Problems
LEDs indicate all system states in the startup sequence. By checking the LEDs,
you can determine when and where the system failed in the startup sequence. If
you have problems after the switch is powered on and the startup sequence is
complete, refer to the software configuration guide for your switch.
After you connect the power cord to the Catalyst 2948G, 2948G-GE-TX,
or 2980G switches, follow these steps:
Step 1
You should immediately hear the system fans begin to operate. If you do not, see
the “Troubleshooting the Power Supply” section on page 5-4. If you determine
that the power supplies are functioning normally and that the fans are faulty,
contact a customer service representative.
Step 2
Check the power supply LEDs as follows:
Step 3
•
The power supply LED should turn green immediately when power is applied
to the switch. The LED should remain on during normal system operation.
•
If the LED turns amber, see the section, “Troubleshooting the Power Supply”
section on page 5-4.
Check that the LEDs on the front panel light as follows:
•
The STATUS LED flashes amber once and stays amber during diagnostic
boot tests. It turns green when the switch is operational (on line). If the
system software is unable to start up, this LED stays amber.
•
The Link LED flashes amber once after diagnostic boot tests, and turns green
when the module is operational (on line). If no signal is detected, the Link
LED turns off. The Link LED blinks amber continuously if the port is bad.
Note
•
After the diagnostic boot tests, the single flash of amber on the Link LED
may occur too quickly to be detected visually.
If a STATUS LED is red or amber, contact a customer service representative
for instructions.

Step 4
If the boot information and system banner are not displayed, verify that the
terminal is set correctly and that it is connected properly to the console port.
Troubleshooting the Power Supply
To help isolate a power subsystem problem, follow these steps:
Step 1
Check the power supply LED:
Note
Power supply LEDs are labeled PSI, PWR, and RPS.
•
If the LED is either off or amber, unplug the power cord, and then plug the
power cord in again.
•
If the LED remains off, there might be a problem with the AC source, or the
power cable. Connect the power cord to another power source (if one is
available).
If the LED then lights, the problem is the first power source.
•
If the LED fails to light after you connect the power supply to a new power
source, replace the power cord.
If the LED still fails to light, the power supply is probably faulty.
Step 2
If a Redundant Power System (RPS) is installed, check the RPS LED:
If the LED is amber or off, repeat the previous procedure to troubleshoot the
second power supply.
Note
If the power supply is a Cisco RPS 675 and the LED is amber, the RPS may be in
standby mode. Press the Standby/Active button on the RPS to put it in active mode
and the LED should then turn to green.

Note
Step 3
If you are using an RPS, do not apply power to the RPS and the switch
simultaneously. Disconnect power from the internal power supply before
turning the power on for the RPS. The RPS contains multiple power
supplies for redundant power protection. Refer to the RPS documentation
for installation and configuration details.
If you are unable to resolve the problem, contact a customer service representative
for instructions.
Contacting Customer Service
If you are unable to solve a startup problem after using the troubleshooting
suggestions in this chapter, contact a customer service representative for

Differential Mode Delay
When an unconditioned laser source designed for operation on a single-mode
fiber (SMF) cable is directly coupled to a multimode fiber (MMF) cable,
differential mode delay (DMD) might occur. DMD can degrade the modal
bandwidth of the fiber-optic cable. This degradation causes a decrease in the link
span (the distance between the transmitter and the receiver) that can be reliably
supported.
The Gigabit Ethernet specification (IEEE 802.3z) outlines parameters for
Ethernet communications at a gigabit-per-second rate. The specification describes
a higher-speed version of Ethernet for backbone and server connectivity using
existing deployed MMF cable. It does this by defining the use of laser-based
optical components to propagate data over MMF cable.
Lasers function at the baud rates and longer distances required for Gigabit
Ethernet. The IEEE 802.3z Gigabit Ethernet Task Force has identified the DMD
condition that occurs in certain circumstances with particular combinations of
lasers and MMF cable. The resulting characteristics create an additional element
of jitter, which limits the reach of Gigabit Ethernet over MMF cable.
When DMD occurs, a single laser light pulse excites a few modes equally within
an MMF cable. These modes, or light pathways, then follow two or more different
paths. The paths might have different lengths and transmission delays as the light
travels through the cable. When DMD occurs, a distinct pulse propagating down
the cable no longer remains distinct or, in extreme cases, might become two
independent pulses. Strings of pulses tend to interfere with each other, making it
difficult to recover data in a reliable fashion.

Appendix C
Differential Mode Delay
DMD does not occur in all deployed fibers; rather, it occurs with certain
combinations of worst-case fibers and worst-case transceivers. Gigabit Ethernet
is the first technology to experience this problem because of its very high baud
rate and its long MMF cable lengths. SMF cable and copper cable are not affected
by DMD.
MMF cable has been tested for use only with LED sources. LEDs create a
condition within a fiber-optic cable referred to as an overfilled launch condition.
The overfilled launch condition describes the way LED transmitters couple light
into the fiber-optic cable in a broad spread of modes. Similar to a light bulb
radiating light in a dark room, the generated light that shines in multiple directions
can overfill the existing cable space and excite a large number of modes. (See
Figure C-1.)
Figure C-1
LED Transmission Compared to Laser Transmission

Laser
Lasers launch light in a more concentrated fashion. A laser transmitter couples
light into only a fraction of the existing modes or optical pathways present in the
fiber-optic cable. (See Figure C-1.)
The solution to DMD in this case is to condition the laser light launched from the
source (transmitter) so that it spreads the light evenly across the diameter of the
fiber-optic cable, making the launch look more like an LED source to the cable.
The objective is to scramble the modes of light to distribute the power more
equally in all modes and prevent the light from being concentrated in just a few

modes. This is in contrast to an unconditioned launch, which, in the worst case,
might concentrate all of its light in the center of the fiber-optic cable, exciting
only two or more modes equally.
A significant variation in the amount of DMD is produced from one MMF cable
to the next. No reasonable test can be performed to survey an installed cable plant

cord for all interfaces using MMF when the link span exceeds 984 feet (300
